将这段MACD源码写一个“积底背”条件选股做预警

编写要求：

请老师根据以下源码写一个条件选股或预警，源码如下： DIFF : EMA(CLOSE,16) - EMA(CLOSE,29); DEA : EMA(DIFF,9); MACD : 2*(DIFF-DEA), COLORSTICK; JC := DEA-DIFF; 绿柱面积:=IF(MACD<0,SUM(MACD,BARSLAST(JC<0)),0); 红柱面积:=IF(MACD>0,SUM(MACD,BARSLAST(JC>0)),0); 本次最低价:=LLV(L,BARSLAST(JC<0)); 本次最高价:=HHV(H,BARSLAST(JC>0)); X1:=IF (MACD<0,BARSLAST(CROSS(DIFF,DEA)),0); 前次绿柱面积:=REF(绿柱面积,X1+1); 前次最低价:=REF(本次最低价,X1+1); Y1:=IF((绿柱面积<0 AND ABS(绿柱面积)=DEA,DIFF,DRAWNULL),COLORRED; 守:IF(DEA>=DIFF,DEA,DRAWNULL),COLORFF9900; 纪:IF(DIFF>=DEA,DEA,DRAWNULL),COLOR00FFFF; 律:IF(DEA>=DIFF,DIFF,DRAWNULL),COLOR00FF00; X2:=IF (MACD>0,BARSLAST(CROSS(DEA,DIFF)),0); 前次红柱面积:=REF(红柱面积,X2+1); 前次最高价:=REF(本次最高价,X2+1); Y2:=IF((红柱面积>0 AND 红柱面积<前次红柱面积 AND 本次最高价>前次最高价 ),1,0); RS2:= MACD>0 AND REF(MACD,1)>0 AND C>前次最高价 AND ABS(红柱面积)

解答：

?DIFF:=EMA(CLOSE,16) - EMA(CLOSE,29);

DEA:=EMA(DIFF,9);
